Abstract: A semiconductor chip or die is mounted at a position on a support substrate. A light-permeable laser direct structuring (LDS) material is then molded onto the semiconductor chip positioned on the support substrate. The semiconductor chip is visible through the LDS material. Laser beam energy is directed to selected spatial locations of the LDS material to structure in the LDS material a pattern of structured formations corresponding to the locations of conductive lines and vias for making electrical connection to the semiconductor chip. The spatial locations of the LDS material to which laser beam energy is directed are selected as a function of the position the semiconductor chip which is visible through the LDS material, thus countering undesired effects of positioning offset of the chip on the substrate.

Abstract: A signal processing circuit includes a filter generating a quantizer input signal from a noise shaping input signal and a quantizer output signal. A quantizer divides the quantizer input signal by a scaling factor to produce a noise shaping output signal and multiplies the noise shaping output signal by the scaling factor to produce the quantizer output signal. Receiver circuitry scales the quantizer output signal by a second scaling factor. A dynamic range optimization circuit compares a current value of the noise shaping input signal to a threshold value, lowers or raises the scaling factor in response to the comparison, and proportionally lowers or raises the scaling factor such that a ratio between the scaling factor and second scaling factor remains substantially constant.
